hi i have a polish pullet. she is a couple of months old and i just noticed something. she is very bony and she eats a pretty good amount of feed (not a lot) and her nostrils are filled with fluid and when she sneezes she squirts out a lot of liquid. and she drank a little to much water and as soon as i picked hr up she spit up a lot of water. she had no food in her crop. and the last thing she had been itching her head so i looked and her whole head was infested with mites and their eggs. i just put seven dust on them about 2 weeks ago. i really need help i love her and i cant bear to loose her. and today i put ACV in her water and she has been drinking that and i just dusted her with seven dust. i need to know asap, her eyes still open and she walks around a little but i am keeping her in a cage by herself with her ACV water and a lot of food. WHAT DO I DO?!?!?!?!?
